Topology preserving edge contraction - Dey, Tamal; Edelsbrunner, Herbert; Guha, Sumanta; Nekhayev, Dmitry (Publications de l'Institut Mathématique, 1999)
We study edge contractions in simplicial complexes and local conditions under which they preserve the topological type. The conditions are based on a generalized notion of boundary, which lends itself to defining a nested hierarchy of triangulable spaces measuring the distance to being a manifold.
